Apple intelligence has kicked me back off to the waitlist, I've been stuck on it for more than 48 hours but the first time I was on the waitlist, it only took 5 minutes.

EDIT: I fixed it! Change your Siri language to any unsupported language and then change it back and it should work!

I updated to macOS 15.1 DB1 when it came out and activated apple intelligence and it was working flawlessly up until two nights ago when I restarted my laptop and apple intelligence was disabled and its showing "Joined Waitlist" and have all the old Siri stuff.

I was going to use the writing tools to proofread my post but can't. 😭
